In 1836, a small group of Texan settlers fighting for their freedom from Mexico fortified an old Spanish mission near the village of San Antonio de Béxar. Surrounded and badly outnumbered by a larger Mexican army, the defenders of the Alamo vowed to fight rather than surrender. Their sacrifice allowed other Texans the opportunity to organize and prepare their army to face the Mexicans, and win freedom for Texas at the Battle of San Jacinto six weeks later. Today the Alamo remains a shrine to liberty, and a symbol of courage and determination in the face of overwhelming odds.

In the early days of American independence, government leaders tried to identify an animal that would represent the new nation. They settled on the bald eagle, a proud raptor that fiercely defends its nest and its family. The eagle has been used to represent government power since the time of the Roman Empire. In 1787 the bald eagle was officially adopted as the emblem of the United States. The eagle is often shown holding an olive branch (representing peace) and arrows (representing war) in its talons. Today the bald eagle remains a living symbol of American strength and values.

The issue of slavery had divided the nation for decades, but problems came to a head after the election of Abraham Lincoln as president in 1860. Fearing that Lincoln would attempt to abolish slavery, the legislatures of 11 southern states voted to withdraw from the United States and create a new nation, the Confederate States of America. This would result in four bloody years of Civil War in which more than 600,000 Americans were killed. The Confederacy adopted several flags between 1861 and 1865; the best known today is the battle flag, which featured a blue saltire cross on a red background. To some people, the Confederate flag is a proud symbol of Southern heritage and bravery. Others, however, view the Confederate flag as a symbol that represents the enslavement and oppression of African Americans. As a result, the Confederate flag is among the most controversial of American symbols.

Between 1892 and 1954, more than 12 million immigrants entered the United States through the Ellis Island processing station in New York harbor. To these immigrants, Ellis Island was a symbol of the American dream—once they passed through its gates, they could start a new life with opportunities that were not available to them in their countries of origin. Today, roughly one-third of our country''s population is descended from those who were processed at Ellis Island, and the facility is now a museum dedicated to American immigration.

Some of the most important documents in American history were composed and debated within the Pennsylvania State House, now known as Independence Hall. In 1776, the Second Continental Congress voted to approve the Declaration of Independence, which said that the American colonies would no longer be subject to the British rule. In 1787, Independence Hall hosted discussions for a new Constitution, which even today remains the foundation of government for the United States. The Liberty Bell, which once hung in the steeple of Independence Hall, has also become an important American symbol. Today, millions of people visit Independence Hall each year to celebrate the origins of America.

On July 8, 1776, the bell in the steeple of the Pennsylvania State House in Philadelphia began to ring, letting the citizens know that an important announcement was about to take place. It was the reading of the Declaration of Independence, a statement by representatives of the 13 American colonies that they would no longer be subject to the rule of the British king. Since then, the Liberty Bell, with its famous crack, has been a symbol of American freedom and patriotism.

In November 1860, Abraham Lincoln was elected as the 16th president of the United States. By the time Lincoln took office in March 1861, the country was in crisis, as 11 states had declared their intention to secede and form a new nation, the Confederate States of America. More than four bloody years of civil war followed. Lincoln managed the government''s effort to put down the rebellion and restore harmony to the country, and in the process set the nation on the path toward ending slavery forever. The Lincoln Memorial on the National Mall in Washington, D.C., commemorates Lincoln''s accomplishments, as well as his personal belief in the dignity and inherent equality of all people. It has been the site of many large gatherings and protests. For millions of Americans, the Lincoln Memorial remains an inspiring symbol of freedom.

For more than six decades, Rock ''n'' Roll music has been a voice of youth. This uniquely American style of music has had an enormous impact on the fashion, lifestyles, and attitudes of young people, both in the United States and elsewhere around the world. During the 1960s, rock music helped to change attitudes toward civil rights for African Americans. In the 1980s, rock helped to subvert the governments of the Soviet Union and its Eastern Bloc satellites, leading to the collapse of Communism. Major rock concert events like the Concert for Bangladesh (1971), Live Aid (1985), and Live 8 (2005) have raised awareness, and money, for worthwhile causes. Rock ''n'' Roll music continues to evolve, as well as to influence self-expression in young people today.

The Statue of Liberty was given to the United States as a gift from the people of France in 1886. It was originally meant as an emblem of the friendship between the two nations, but over the years it has come to mean much more. The Statue of Liberty has come to represent the promise of America—a promise that drew tens of millions of immigrants from other countries, seeking greater freedom and opportunities. For many of these immigrants, Lady Liberty was the first thing they saw when they arrived in the United States. The Statue of Liberty has also served as a symbol of freedom for those who are oppressed throughout the world.

In 1787, the young United States was suffering from a governmental crisis. The original form of government created to unite the 13 states did not work well, and it was clear that something new was needed. In Philadelphia, representatives of the states met to create a new system of government. The document they produced, the U.S. Constitution, remains the framework for our government more than 225 years later. The U.S. Constitution sets out the duties of the various branches of the federal government, as well as the powers reserved by the states. It also delineates the rights that every individual possesses. To understand what being an American means, all citizens should understand the U.S. Constitution.

For more than 200 years, U.S. presidents have lived and worked in the executive mansion at 1600 Pennsylvania Avenue in Washington, D.C.—commonly known as the White House. The executive mansion received its nickname in 1798, when its stone exterior was painted white to seal it from moisture and prevent cracking. As the official home of the president, the White House has come to symbolize the power and authority of the U.S. government. Within its walls, decisions are made that affect the lives of all Americans and, very often, the lives of millions of people around the world. Today, many people view the White House as a symbol of leadership and democracy.

It is said that the inspiration for the character of Uncle Sam was a man named Sam Wilson, who provided food for the U.S. Army during the War of 1812. By the 1830s, the figure of Uncle Sam had become a personified image of America, commonly used by newspaper and magazine cartoonists to represent the U.S. government''s decisions and policies. Perhaps the best-known image of Uncle Sam was created in 1917, during the First World War—a stern, white-haired man wearing star-spangled clothing, encouraging Americans to do their part to support their nation. Uncle Sam remains an important symbol of the United States and the policies and activities of our government.

George Washington played a vital role in the founding of the United States. He was commander of the Continental Army during the American Revolution, presided over the convention that drafted the U.S. Constitution, and served as the first president. To honor Washington for his contributions, in the 1840s construction began on a monument in his honor—a stone obelisk that rises more than 550 feet in the sky above the capital. It took nearly 40 years before the monument was completed. Each year, millions of people visit the Washington Monument, which represents the achievements of George Washington, and the gratitude that Americans feel toward the "Father of our Country."
